using docker-compose on old ubuntu versions #229

Closed dufywihi closed 5 years ago

dufywihi commented 5 years ago

using xenial, installed docker:

https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

then installed docker-compose from the ubuntu repos (no package called docker-compose found in docker repos)

then git cloned the pb repo into /opt. then ran:

docker-compose up

ERROR: Version in "./docker-compose.yaml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

the docker-compose version found in xenial is v1.8.0. what am i getting wrong here?

what am i getting wrong here

Your docker-compose version is too old, as said poorly in the error message. 1.8.0 supports compose file version <=2.0 while pb specifies =3.2 (first introduced in docker-compose 1.12.0).

I suggest the "Linux" instructions here (curl + chmod):

https://docs.docker.com/compose/install/#install-compose

You'll also need a compatible docker engine/runtime, which should be version 17.04.0 or later. You might consider just not using such an ancient ubuntu release, which would fix all of this for free.
